Rathore DPS
Uranium and other heavy toxic elements distribution in the drinking water samples of SW-Punjab, India, are presented. It is mandatory in all publications to clearly mention the instrumental details to ensure reliability of measurement results. The same fluorescence enhancing reagent should be used for calibration of the instrument and subsequent measurement of uranium in samples. Using the above procedure for pre-concentration and keeping in view of the characteristic concentration of these heavy metals using flame Atomic Absorption Spectrophotometer, their determination at μgl-1 concentration levels is practically impossible. Interpretation and conclusions based on such unreliable results on uranium and other heavy metals will be highly misleading for their health risk, toxicological risk and chemical toxicity risk assessments
